What is the battery model for the Mercedes GLE key?
1 Answers
The battery models are CR2032 and CR2025-3v. These are lithium manganese dioxide batteries, named according to the IEC standard. Among them: C - indicates a chemical battery system with lithium metal as the negative electrode and manganese dioxide as the positive electrode; R - indicates that the battery shape is cylindrical; if it is square, F is used instead; 20 indicates the battery diameter is 20mm; 32 represents the battery height of 3.2mm; 25 represents the battery height of 2.52mm; The nominal voltage is 3.0V, the endpoint voltage is 2.0V, and the rated capacity is around 200mAh. CR2032 typically has a lifespan of 5 years. If the manufacturer's production level is low or quality control is poor, its lifespan will be significantly shortened. Domestic first-tier brand batteries can generally guarantee this lifespan. Under ideal usage conditions (sealed, room temperature, no moisture interference, etc.), the lifespan can be further extended to 8 years or even 10 years. The usage time of a car remote key battery is closely related to the frequency of use. The more frequently it is used, the shorter the lifespan will be. If the remote key battery runs out, the mechanical key can be used directly to unlock and start the vehicle. The batteries used in car remote keys are button cells, mainly including models: CR2016, CR2025, CR2032, and CR2450. For the specific model used in each key, owners can refer to the battery model in the user manual for replacement. Button-type CR2016 battery: This is one of the most commonly used car remote batteries. The battery voltage is 3V, while most car key batteries are powered by 9V, so all three batteries need to be replaced each time. Examples include: Guangben, Toyota, Volkswagen, Mazda, etc. CR2016 specifications: battery diameter is 20mm, thickness is 1.6mm. Button-type CR2025 battery: Its usage rate is much lower than CR2016, but some car keys still use it. It is thicker than the 2016 model but has a relatively higher storage capacity. CR2025 specifications: battery diameter is 20mm, thickness is 2.5mm. This type of battery is also commonly used in audio remotes. Button-type CR2032 battery: Its thickness is twice that of CR2016. The 3V-CR2032 lithium manganese battery belongs to the lithium-manganese dioxide structure. The positive electrode material is chemically stable manganese dioxide, the negative electrode material is lithium metal, and the electrolyte is a lithium battery electrolyte. The main components of the electrolyte are dimethoxyethane, propylene carbonate, and lithium perchlorate. Its shape resembles a button, hence the name button lithium battery or lithium manganese button battery. Button-type CR2450 battery: Compared to the other three models, it is thicker and larger, with a diameter of 24.5mm and a height of 5.0mm. The rated current value for CR2450 is 0.2mA, mainly used in low-power electronic products. Generally, such batteries can provide an output current of 0.001mA to 5mA, with a continuous output current of up to 15mA and a flash output current of up to 30mA, meeting the requirements of most small electronic products for light emission, sound production, and RF output.
